Alzheimers health...It's huh time, huh, huh, huh,

The mother in law has started something new, a slight annoyance. Just when started to get used to her mumbling to herself and her saying "Oh I am just talking to myself" and not wanting to share what she was mumbling about she started something new.

It doesn't matter what is on the TV, after every sentence said, she says "HUH" after. She does this for hours. Whoa, it is annoying, but I say nothing. The other day even during the huh's she started talking to herself, I asked what she was saying. The show was talking about Hover Damn but she said "They are telling me about the WAR", I should have said nothing.
Noooo, I was stupid and said the show was actually about Hover Damn, I know better.

Yesterday she was fixated on the number 21. She was telling neighbors "21" no matter the story it was 21 years. 21 years at the same employment, 21 years of marriage, she was married at 21 everything was 21. I said nothing, it was clear, it had to be clear to the person she was talking too something didn't add up. I laugh now, not in front of her of course.
